Overview of Miracle Gro Potting Soil

Miracle Gro Potting Mix is a go-to potting soil for many gardeners. It contains a blend of sphagnum peat moss, perlite, fertilizer, and a wetting agent. The mix provides a lightweight and porous growing medium that helps prevent soil compaction while still retaining just the right amount of moisture and nutrients.

Some of the key benefits of Miracle Gro potting mix include:

Miracle Gro Potting Mix
  • Nutrition – Contains Miracle Gro continuous release plant food to feed plants for up to 6 months.
  • Lightweight & porous – The peat moss and perlite create lots of air space for healthy root development.
  • pH balanced – Comes pre-balanced to an optimal pH for most plants.
  • Wetting agent – Helps soak up water thoroughly and reduces water repellency.
  • Ready to use – Comes prepared and ready to use right out of the bag.

The Miracle Gro potting mix works well for container gardening and re-potting indoor and outdoor plants.

It provides a clean, sterile starting medium with steady fertilization. The mix is designed to be well-aerated and quick draining.

Some downsides are that it may dry out faster than denser soil mixes. The light mix can also be prone to gnats if kept overly moist. It may need additional compost or coconut coir added for moisture retention.

Overview of Miracle Gro Moisture Control Potting Mix

Miracle Gro also offers a Moisture Control version of their potting mix. This mix has the same base ingredients as the original formula, but with extra additives to help the soil better retain moisture.

The Moisture Control mix contains:

  • Peat moss, perlite, fertilizer, and wetting agent like the original mix
  • Plus extra coconut coir and polymers to increase water retention

Some of the benefits of the moisture control potting mix:

  • Excellent water retention – The coir and polymers allow the soil to hold onto more moisture longer.
  • Reduced drying out – Stays moist longer than regular potting mix, helping prevent wilting.
  • Lasts up to 30% longer – Requires less frequent watering compared to standard soils.
  • Feeds up to 6 months – Contains the same continuous release Miracle Gro plant food.
  • Lightweight & porous – Still provides the aeration benefits of a peat/perlite mix.

The Miracle Gro moisture control mix is ideal for gardeners who tend to underwater plants and want their soil to stay moist longer. It’s great for container plants prone to drying out like petunias, vegetables, and patio containers. The mix allows gardeners to worry less about frequent watering.

Some downsides are that it may stay overly wet if overwatered. The moisture retention can lead to gnats if the soil isn’t allowed to dry out occasionally. The mix also comes at a higher cost than traditional potting soil.

Comparing Key Features of Miracle Gro Potting And Moisture Control Potting Mix

Now that we’ve covered the basics of each potting mix, let’s compare some of the key features and differences:
